Solid-State HVAC Sensor eliminates need for Freeze Stat.

Press Release Summary:

Designed to protect chillers in air handling equipment used by commercial buildings, Chill-Out(TM) Combination Sensor replaces Freeze Stat but has 2 sensors: one low-temp cut-out sensor and one independent averaging-temp sensor. Dual-sensor package delivers accurate measurements and eliminates need to install separate averaging sensor. Mounted in any direction, product offers low-temp sensitivity within 12 in. segment and has no capillary tubes to break, leak, or kink.

New Solid-State HVAC Sensors Eliminate Freeze Stat

Stop wrestling with potentially hazardous, fragile gas-filled capillaries and move to a greener solution! Minneapolis, Minn., July 15, 2009-Minco, a designer and manufacturer of critical components for critical applications, has a new line of heating, ventilating and air conditioning (HVAC) temperature sensors designed to protect chillers in air handling equipment in commercial buildings. The new sensor line is called the Chill-Out(TM) Combination Sensor. Visit Minco's Total Cost of Ownership (TCO) Calculator to see your true savings if you install both a freeze stat low limit device and an averaging sensor. Most schools, hospitals, office complexes and other commercial buildings use a device called a Freeze Stat, along with an averaging sensor to protect against freezing temperatures. The solid state, low temperature cut-out Chill-Out sensor has a number of advantages over traditional Freeze Stat/averaging sensor technology:

  • Minco's Chill-Out(TM) Combination Sensor replaces the Freeze Stat, but, unlike the Freeze Stat, it has two sensors in one easy-to-install package. One is a low-temp cut-out sensor and one is an independent averaging-temp sensor. This dual sensor package delivers accurate measurements and eliminates the need to install a separate averaging sensor.
  • Saves $13K-$35K over a typical Freeze Stat/averaging sensor installation.
  • There are no capillary tubes to break, leak or kink.
  • Considered a "green" product by the industry as it is solid state and has no harmful gases or chemicals.
  • Easy mounting in any direction. Horizontal orientation is not required.
  • Relay changes state to deliver a failure detection signal in the event of a power loss.
  • Low-temp sensitivity within a 12-inch segment, versus 18 inches with gas-filled capillary tubes.
  • Easily formed aluminum or ultra flexible PVC coated galvanized armor sensor case.
  • 4 to 20 mA temperature loop output available with optional Temptran(TM) transmitter.
  • No diaphragm case needed. Clearly, the Minco Chill-Out Combination Sensor offers many benefits over Freeze Stat technology.
